Validation of Farsi Translation of the Ocular Surface Disease Index.

ABSTRACT: To develop and validate a Farsi version of Ocular Surface Disease Index (OSDI) for the Iranian population.This study was a translation and cross-cultural adaptation and validation of Farsi version of OSDI. Four bilingual (English-Persian) individual including three physicians and one native English teacher were asked to translate the original English OSDI questionnaire in Farsi. Following back and forth translation, integration and pilot check, the translation team came to consensus on translation. Consecutive patients visited in ophthalmology clinic, underwent comprehensive general ophthalmology exam and specific assessments for dry eye including non-anesthetic Schirmer's test, fluorescein tear break-up time, Fluorescein and Rose Bengal staining and Farsi OSDI (F-OSDI). F-OSDI was again rechecked within 2-7 days after the examination.Forty-four participants were enrolled into study. Thirty-two (72.7%) were male and 12 (27.3%) female. Mean age of participants was 45.5 (SD = ±15.97, range = 18-80) years. Twenty five percent were less than 31 years old and 10% percent older than 65. The cronbach's alpha for the questionnaire was 0.807. Questions number 7, 8 showed excellent, and question12 showed good internal consistency, respectively. There was a significant correlation between all pre measures and post assessments.The obtained F-OSDI showed acceptable internal consistency and test-retest reliability. This F-OSDI could be used for assessment of dry eye, ocular surface discomfort and quality of life in Iranian and Farsi speaking populations.

Project description:We developed, and examined the reliability and validity of, a Japanese version of the Dysphagia Handicap Index (DHI; DHI-J), which is a self-reported measure to assess the quality of life (QOL) of individuals with dysphagia.The DHI-J was developed via the back-translation method: the DHI was translated into Japanese and then translated back into English by a native English speaker. The back translation was discussed with and approved by the DHI's lead author. A total of 229 patients (119 males, 110 females; median age: 66 years) who underwent videofluorography at our hospital between January and December 2013 and 65 controls (23 males, 42 females; median age: 44 years) were included in the study. All the subjects completed the DHI-J and self-reported their dysphagia severity. Twenty-three patients repeated the procedure 1 week later. Patients' swallowing function was classified as "normal", "moderately impaired", or "severely impaired", and the DHI-J total scores were compared between the severity groups.The internal consistency of the DHI-J was high (Cronbach's ?=0.95), as was the test-retest reliability of the 23 patients who answered the questionnaire twice (intraclass correlation coefficient =0.98, P<0.01). The DHI-J total score and its three subscale scores were significantly higher among the patients than among controls. A significant correlation (?=0.85) was observed between the DHI-J total score and self-reported dysphagia severity score. Regarding the comparison of DHI-J scores by severity groups, the DHI-J total scores significantly differed between the normal and moderately impaired groups, and the normal and severely impaired groups. However, the moderately and severely impaired groups showed no significant difference in scores.The DHI-J is a reliable and valid questionnaire for assessing the QOL of patients with dysphagia. However, we did not survey patients with cerebrovascular diseases; thus, the questionnaire must be validated for that patient group.

Project description:ObjectiveTo find preoperative screening criteria for dry eye syndrome (DES) that present after successful endoscopic dacryocystorhinostomy (EDCR).MethodsWe retrospectively analyzed medical records of 110 patients who underwent EDCR for nasolacrimal duct obstruction. DES diagnostic criteria were defined as tear break-up time (TBUT) less than 10 seconds, and ocular surface disease index (OSDI) score greater than 13 points. After EDCR, patients were divided into DES group and control group according to the DES diagnostic criteria. Preoperative OSDI score alone or in combination of preoperative TBUT and OSDI score were used to find screening criteria, which could discriminate the two groups preoperatively with a high positive predictive value (PPV). Criteria A was set same as the diagnostic criteria of DES, and Criteria B and C were set to improve PPV by increasing specificity while maintaining similar sensitivity to Criteria A.ResultsThirty patients (27.3%) were diagnosed with DES after EDCR, while 80 patients (72.7%) were normal. In patients with DES, preoperative TBUT was not different (p = 0.851), but OSDI score was significantly higher (p<0.001). Criteria A showed a sensitivity of 73.3%, specificity of 55.0%, and PPV of 38.0%. Criteria B and C excluded preoperative TBUT, which had no difference between the two groups, and set screening criteria with preoperative OSDI score alone. Criteria B (preoperative OSDI score of 19.6 points or more) showed a sensitivity of 75.0%, specificity of 60.6%, PPV of 41.7% and AUC of 0.739 (p < 0.001). Criteria C was consisted of 5 out of 12 OSDI items that showed significant differences between the two groups; blurred vision, reading, working with a computer, low humidity, and air conditioning. Criteria C (preoperative 5-item OSDI score of 24.4 points or more) was a better predictability, with a sensitivity of 75.0%, specificity of 71.3%, PPV of 49.5%, and AUC of 0.804 (p < 0.001). The AUC of Criteria C was significantly higher than that of Criteria B (p = 0.0037).ConclusionDES occurred after successful EDCR in 27.3% of patients, and an OSDI questionnaire helped to screen DES. The predictability could improve using the modified OSDI score which showed noticeable difference in five OSDI items before and after EDCR.
